The first region (220a) may include a rigid region, and the second region (220b) may include a flexible region and / or a rigid region. For example, the patch antennas (224, 225) may be placed in the rigid region of the second region (220b), but are not limited thereto.

One side of the second region (220b) may be connected to the first region (220a), and the other side of the second region (220b) may be connected to a mmWave antenna module (230).

[0041] According to one embodiment, the mmWave antenna module (230) may be equipped with other patch antennas for 5G communication.

[0042] According to one embodiment, the electronic device (101) may include at least one antenna (e.g., a patch antenna) for 5G communication and / or 6G communication on a PCB (210) or on an auxiliary circuit board connected to the PCB (210).

[0043] According to one embodiment, the housing of the electronic device (101), the antenna (e.g., patch antenna), and / or the transmission power through the antenna (e.g., power amount, radiation pattern, radiation direction) may be designed with consideration of the human body effects of electromagnetic waves. Each country establishes regulations regarding the human body effects of electromagnetic waves (e.g., specific absorption rate; SAR) in consideration of the effects of electromagnetic waves on the human body. For example, if the SAR measured by the electronic device exceeds a set standard, the impact on the human body can be reduced by performing power backoff. As the transmission power decreases during the power backoff process due to the SAR, the transmission performance of the antenna may deteriorate. This deterioration in antenna transmission performance leads to reduced coverage and a decrease in uplink transmission speed (e.g., throughput), which may have a negative impact on the actual user experience.

[0044] Figure 3 is a graph showing the relationship between power and throughput according to various embodiments.

[0045] Referring to Fig. 3, as the transmit power at the near-cell location is reduced from 25.5 dBm to 23.5 dBm, the average throughput of the PUSCH (physical uplink shared channel) data can be reduced from 121.689 Mbps to 100.633 Mbps. As the transmit power at the mid-cell location is reduced from 25.5 dBm to 23.5 dBm, the average throughput of the PUSCH data can be reduced from 108.923 Mbps to 73.392 Mbps. As the transmit power at the far-cell location is reduced from 25.5 dBm to 23.5 dBm, the average throughput of the PUSCH data can be reduced from 40.721 Mbps to 21.847 Mbps. For example, if an electronic device reduces transmission power due to power backoff by SAR, the average throughput of uplink data (e.g., PUSCH) may be reduced regardless of where the electronic device is located from the cell center (e.g., short distance, medium distance, or long distance), as shown in FIG. 3.

[0046] With the advancement of communication technology, various communication access technologies are developing, and as wireless communication functions are being incorporated into various mobile devices such as smartphones, tablets, smartwatches, and wireless earphones, the use of frequency bands above 6 GHz is becoming widespread. Table 1 below shows examples of frequency bands according to each communication technology.

[0047] Communication technology Frequency band LTE / 5G(NR) / 6G 1.8GHz, 3.5GHz, 28GHz, 7 / 8GHz, 15GHz Wi-Fi 2.4GHz / 5GHz, 6GHz or higher BT 2.4GHz, 5GHz / 6GHz or higher UWB 6GHz ~ 10GHz WPT 150kHz, 6.78MHz NFC 13.56MHz

[0048] According to one embodiment, the 7.125–8.4 GHz and 14.8–15.35 GHz bands are being considered as 6G communication bands. For the bands above 6 GHz considered as 6G communication bands, absorbed power density (APD) standards have been established as regulations regarding the human health effects of electromagnetic waves. For example, in 6G communication, standards limiting the APD may be applied as criteria for evaluating the human health effects of near-field electromagnetic waves on electronic devices used in close proximity to the human body. According to various embodiments, the aforementioned SAR regulations are applied to frequency bands below 6 GHz, and APD regulations are applied to frequency bands above 6 GHz, thereby reducing the impact of electromagnetic waves on the human body. SAR regulations measure the amount of energy absorbed by human tissue in watts per kilogram (W / kg), while APD regulations measure the power density incident on the human body in milliwatts per square centimeter (mW / cm²). 2 ) or Watt / Square Meter ((W / m²) 2 It can be measured as ). In the case of APD, which evaluates the impact on the surface of human tissue, it can be relatively more affected by the antenna's near-field performance. In contrast, the antenna's transmission performance can be relatively more affected by its far-field performance.

[0049] FIG. 4a is a diagram showing an APD according to antenna feeding conditions according to various embodiments. FIG. 4b is a diagram showing an APD according to antenna feeding conditions according to various embodiments.

[0050] Referring to FIG. 4a, when a feeding pad (or feeding point) (412) is positioned at the center of the rear of the patch antenna (411) as shown in the upper left and lower right, the antenna gain is 6.84 dBi and the APD may be 293 W / m². When a feeding pad (422) is positioned at the upper rear of the patch antenna (421) as shown in the upper right and lower right, the antenna gain is 7.09 dBi and the APD may be 326 W / m². For example, as the position of the feeding pad (or feeding point) is moved upward, the antenna gain increases, but the APD may increase.

[0051] Referring to FIG. 4b, a feeding pad (432) can be positioned via a feed line (433) connected to a patch antenna (431) as shown in the upper and lower left. The feeding pad (432) may include a feed point (432a). Depending on various embodiments, if shielding is achieved by placing a shielding member (434) on the feeding pad (432) (e.g., covering it), the antenna gain may be 6.5 dBi and the APD may be 153 W / m². Depending on various embodiments, if there is no shielding member on the feeding pad (442), the antenna gain may be 6.3 dBi and the APD may be 170 W / m². As shown in the upper and lower right, a feeding pad (442) can be positioned via a feed line (443) connected to a patch antenna (441). The feeding pad (442) may include a feed point (442a). Depending on various embodiments, if there is no shielding member on the feeding pad (442), the antenna gain may be 6.3 dBi and the APD may be 170 W / m². For example, if the feeding pad (432) is shielded by the shielding member (434), the antenna gain can be increased and the APD can be lowered. Additionally, if FIG. 4a, in which a feed portion (e.g., feeding pad (412, 422)) is formed on a radiator (e.g., patch) of a patch antenna (411, 421), is compared with FIG. 4b, in which the radiator (e.g., patch) of a patch antenna (431, 441) and the feed portion (e.g., feeding pad) are spaced apart from each other, the greater the distance between the radiator (e.g., patch) and the feed portion (e.g., feeding pad) as in FIG. 4b, the APD can be lowered at a greater rate compared to the amount by which the antenna gain is reduced.

[0052] According to one embodiment, an antenna radiator and a feed unit that are spaced apart from each other may be connected via a feed line (e.g., a transmission line). According to one embodiment, the feed unit may include an antenna-side feed unit connected to the radiator via a feed line and a transmission line-side feed unit connected to the RFIC (215) via a transmission line. For example, the antenna-side feed unit and the transmission line-side feed unit may be spatially separated to form an indirect feed (i.e., coupling feeding) in which a high-frequency signal is coupled and transmitted. For example, each of the antenna-side feed unit and the transmission line-side feed unit may be formed as a conductive pad. For example, the antenna-side feed unit and the transmission line-side feed unit may supply current using at least one of electromagnetic induction or capacitive coupling.

[0053] According to one embodiment, the feed section (or feed portion) may be wider than the feed line (e.g., RF path, transmission line, signal path). For example, the feed line may include a microstrip line, strip line, or waveguide matched to a specific impedance value (e.g., 50 ohms). For example, the feed section may be formed of a conductive pad of a specific shape (e.g., square, circular). For example, the feed section may be connected to at least one of circuit elements for impedance matching (e.g., capacitor, inductor, resistor, or ground). For example, the feed section may be positioned in close proximity to the circuit elements for impedance matching.

[0054] Various embodiments of the present disclosure describe methods for selecting (or switching) an RF transmission path based on the proximity of an object (e.g., a human body) based on the difference between near-field performance and far-field performance according to the antenna feeding method. Each patch antenna (224, 225) (e.g., antenna radiator) may include a plurality of feed points, for example, including a first feed point and a second feed point.

[0055] According to one embodiment, the first feed point may correspond to a first feeding pad (or first feed section) formed on the antenna radiator. The first feed point may be connected to an RFIC (215) via a first RF path (or first signal path). A transmission signal from the RFIC (215) may be supplied directly to the antenna radiator through the first feed point (i.e., direct feeding). For example, the current density of the transmission signal on the first RF path may be highest at the first feed point formed on the antenna radiator.

[0056] According to one embodiment, a second feed point formed on an antenna radiator may be connected via a feed line (e.g., a transmission line) to a second feeding pad (or second feed section) spaced apart from the antenna radiator. The second feed point may be connected to an RFIC (215) via a second RF path (or second signal path) different from the first RF path. For example, the current density of the transmitted signal on the second RF path may be highest at the second feeding pad spaced apart from the antenna radiator. The second feeding pad may be further away from the APD measurement location compared to the first feed point. As the second feeding pad is spaced apart from the antenna radiator, the amount of degradation in the antenna's far-field performance and the amount of degradation in its near-field performance may differ. For example, when the RFIC (215) transmits a transmission signal of a specified power to the antenna, if the second RF path is selected, the intensity of the electromagnetic wave measured at a distance from the antenna is reduced to some extent compared to the case where the first RF path is selected, but the intensity of the electromagnetic wave measured at a relatively close distance may be reduced more than at a distance. According to one embodiment, the second RF path may include a portion in which the high-frequency transmission signal sent from the RFIC (215) is coupled and transmitted (e.g., coupling feeding) between two spatially separated conductors (e.g., antenna-side feed and transmission line-side feed).

[0057] According to one embodiment, the electronic device (101) can be configured such that when an external object (e.g., a human body) approaches the electronic device (101) to satisfy a certain standard, an RF signal is supplied to a patch antenna (224, 225) (e.g., an antenna radiator) through a second RF path (e.g., an RF path using coupling feeding), and when an external object (e.g., a human body) does not approach the electronic device (101), an RF signal is supplied to a patch antenna (224, 225) (e.g., an antenna radiator) through a first RF path (e.g., an RF path using direct feeding). Accordingly, when an external object (e.g., a human body) approaches the electronic device, the RF signal is transmitted through an RF path with relatively low near-field performance, thereby allowing the electromagnetic waves generated by the electronic device (101) to satisfy APD regulations and / or SAR regulations without power backoff. For example, by utilizing the principle that the measurement value for APD decreases as the distance from the sensing area for APD to the feeding pad (or feeding point) to which the transmission line is connected from the antenna (e.g., a patch antenna) increases, APD regulations can be satisfied (or complied with) without power backoff even if an external object approaches the electronic device.

[0058] According to one embodiment, the electronic device (101) may select an RF path (or feeding method) between the RFIC (215) and the patch antenna (224, 225) based at least partly on the strength of the power received from the base station and / or the strength of the transmission power of the electronic device (101). For example, if the electronic device (101) receives a weak electric field due to being located more than a certain distance from the base station or due to an obstacle, the base station may instruct the electronic device (101) to transmit an uplink signal with a power greater than a certain level. For example, based on a determination that an external object (e.g., a human body) is in close proximity (or contact) to the electronic device (101) and that the transmission power of the electronic device (101) satisfies a predefined criterion, the electronic device (101) may supply current to the antenna using a second RF path (or coupling feeding). For example, if an external object (e.g., a human body) comes into close proximity (or contact) with the electronic device (101) and the transmission power of the electronic device (101) does not satisfy a predefined standard, the electronic device (101) may supply current to the antenna using a first RF path (or direct feeding). For example, if the received electric field from an external electronic device (e.g., electronic device (102), electronic device (104), electronic device (108), access point, or base station) is lower than a specific value, the electronic device (101) may be configured to transmit a signal at a specified maximum power. The specified maximum power may be 26 dBm when a communication connection corresponding to a second power class is established, and 23 dBm to 24 dBm when a communication connection corresponding to a third power class is established. For example, based on the determination that an external object (e.g., a human body) approaches (or contacts) the electronic device (101) and the transmission power of the electronic device (101) is set to maximum power, the electronic device (101) can supply current to the antenna using a second RF path (or coupling feeding).For example, if an external object (e.g., a human body) approaches (or contacts) the electronic device (101) and the transmission power of the electronic device (101) is not set to maximum power, the electronic device (101) may supply current to the antenna using a first RF path (or direct feeding). According to one embodiment, if the receiving electric field of the electronic device (101) is lower than a specific value and it is determined that an external object (e.g., a human body) is approaching or contacting the electronic device (101), the electronic device (101) may supply current to the antenna using a second RF path (or coupling feeding).

[0059] FIG. 5 illustrates a block diagram of an electronic device according to various embodiments.

[0060] Referring to FIG. 5, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a plurality of antennas, a switch (510) (e.g., a first switch (511), a second switch (512)), a first antenna (521) (e.g., a first radiator), and a second antenna (522) (e.g., a second radiator), and a sensing circuit. Each of the first antenna (521) and the second antenna (522) may be a component of a set of antennas composed of a plurality of antennas. Each of the first antenna (521) and the second antenna (522) may correspond to a patch antenna (224) and a patch antenna (225). However, the type of antenna is not limited to a patch antenna. The sensing circuit may include a sensing unit (531) (or sensor) and a sensor IC (532). The sensing unit (531) may include a sensing pattern. The sensing pattern may be positioned in close proximity to the first antenna (521) and / or the second antenna (522). The sensing pattern may each include one or more sensors (e.g., conductors) positioned between a radiator (e.g., a patch) and a radiator (e.g., a patch). The switch (510), the first antenna (521), the second antenna (522), and the sensing unit (531) may be positioned on a first surface (501a) of a substrate (e.g., a PCB or an FPCB) (501), and the sensor IC (532) may be positioned on a second surface (501b) opposite to the first surface (501a) of the substrate (501). The sensing unit (531) may be positioned between the first antenna (521) and the second antenna (522). The arrangement or position of each component shown in FIG. 5 is exemplary and is not limited thereto. For example, the switch (510) and / or sensor IC (532) may be placed on a printed circuit board (e.g., PCB (210)) where the RFIC (215) is located, and the sensing unit (531) may be placed on a printed circuit board (e.g., FPCB (220)) where the first antenna (521) and the second antenna (522) are located.

[0061] According to various embodiments, the switch (510) (e.g., the first switch (511), or the second switch (512)) may be connected to at least one of the first antenna (521) or the second antenna (522) through at least one of the first transmission line (541), the second transmission line (542), the third transmission line (543), and the fourth transmission line (544). For example, the first switch (511) may be connected to the first antenna (521) through the first transmission line (541) or the second transmission line (542). The second switch (512) may be connected to the second antenna (522) through the third transmission line (543) or the fourth transmission line (544). According to one embodiment, the switch (510) (e.g., the first switch (511), or the second switch (512)) may be included within the modem (211), the IF / RFIC module (213), or the RFFE (217). According to one embodiment, the switch (510) (e.g., the first switch (511), or the second switch (512)) may be provided as a separate module. According to one embodiment, the switch (510) may transmit an RF signal (or, transmission signal, transmission power, transmission current) output from the RFIC (215) to the first antenna (521) (or the second antenna (522)) between the RFIC (215) and the first antenna (521) (or the second antenna (522)). For example, the switch (510) (e.g., the first switch (511), or the second switch (512)) may refer to at least one of hardware, software, or firmware that includes a structure capable of selecting one of a plurality of transmission lines based on at least one of the proximity of an external object or the strength of the transmission power according to a command of the processor (e.g., the processor (210)).

[0062] According to one embodiment, the first switch (511) may be configured to select one of the first transmission line (541) and the second transmission line (542) connected to the first antenna (521). According to one embodiment, the first switch (511) may maintain the connection of the first antenna (521) with the other transmission line while transmitting an RF signal to the selected transmission line among the first transmission line (541) and the second transmission line (542). According to one embodiment, the first switch (511) may be configured so that when one of the first transmission line (541) and the second transmission line (542) is connected to the first antenna (521), the other one is not connected to the first antenna (521).

[0063] According to various embodiments, one side of the first transmission line (541) may be connected to the first switch (511), and the other side of the first transmission line (541) may be connected to the first antenna (521) through the first feeding pad (551) (or feed section). For example, the first feeding pad (551) may be located on the surface of the substrate (501) where the first antenna (521) is placed (e.g., the first surface (501a)). An RF (radio frequency) signal may be transmitted from the first switch (511) to the first antenna (521) through the first transmission line (541) and the first feeding pad (551). For convenience of explanation, the path through which the RF signal is transmitted from the first switch (511) to the first antenna (521) via the first transmission line (541) and the first feeding pad (551) may be referred to as the 'first RF path'. The first RF path may be referred to as an RF path utilizing 'direct feeding' as it is directly connected to the first feeding pad (551) via the first transmission line (541), but is not limited to this term.

[0064] According to various embodiments, one side of the second transmission line (542) may be connected to the first switch (511), and the other side of the second transmission line (542) may be connected to a first coupling pad (552b) (e.g., transmission line side feed) which is coupled to a second feeding pad (552a) (e.g., antenna side feed) connected to the first antenna (521). According to various embodiments, the second feeding pad (552a) may be connected to the first antenna (521) via a first feeding line (552c). The second feeding pad (552a) may also be directly connected to the first antenna (521) without the first feeding line (552c). For example, the second feeding pad (552a) may be located on the inside of the substrate (501) at a first distance from the surface where the first antenna (521) is placed (e.g., the first surface (501a)). For example, the first coupling pad (552b) may be located on the inside of the substrate (501) at a second distance from the surface where the first antenna (521) is placed (e.g., the first surface (501a)). The second distance may be longer than the first distance. When an RF signal is transmitted from the first switch (511) to the second transmission line (542), the RF signal may be transmitted to the first antenna (521) through wireless coupling between the first coupling pad (552b) and the second feeding pad (552a). For convenience of explanation, the path through which the RF signal is transmitted from the first switch (511) to the first antenna (521) via the second transmission line (542), the first coupling pad (552b), and the second feeding pad (552a) may be referred to as the 'second RF path'. The second RF path may be referred to as an RF path utilizing 'coupling feeding' as it transmits the RF signal by coupling with the second feeding pad (552a) through the first coupling pad (552b), but is not limited to the above term.

[0065] According to various embodiments, at least one of the second feeding pad (552a) and / or the first feeding line (552c) connecting the second feeding pad (552a) to the first antenna (521) may be omitted. For example, an RF signal may be transmitted to the first antenna (521) by coupling between the first coupling pad (552b) and the first antenna (521). For example, the first coupling pad (552b) may have substantially the same area as the first antenna (521).

[0066] According to one embodiment, the second switch (512) may be configured to select one of the third transmission line (543) and the fourth transmission line (544) connected to the second antenna (522). According to one embodiment, the second switch (512) may maintain the connection of the second antenna (522) with the other transmission line while transmitting an RF signal to the selected transmission line among the third transmission line (543) and the fourth transmission line (544). According to one embodiment, the second switch (512) may be configured so that when one of the third transmission line (543) and the fourth transmission line (544) is connected to the second antenna (522), the other one is not connected to the second antenna (522). According to various embodiments, one side of the third transmission line (543) may be connected to the second switch (512), and the other side of the third transmission line (543) may be connected to the second antenna (522) through the third feeding pad (553) (or feed section). For example, the third feeding pad (553) may be located on the surface of the substrate (501) where the second antenna (522) is placed (e.g., the first surface (501a)). An RF signal may be transmitted from the second switch (512) to the second antenna (552) through the third transmission line (543) and the third feeding pad (553). For convenience of explanation, the path through which the RF signal is transmitted from the second switch (512) to the second antenna (552) via the third transmission line (543) and the third feeding pad (553) may be referred to as the 'third RF path'. The third RF path may be referred to as an RF path utilizing 'direct feeding' as it is directly connected to the third feeding pad (553) via the third transmission line (543), but is not limited to this term.

[0067] According to various embodiments, one side of the fourth transmission line (544) may be connected to the second switch (512), and the other side of the fourth transmission line (544) may be connected to a second coupling pad (554b) (e.g., transmission line side feed) which is coupled to a fourth feeding pad (554a) (e.g., antenna side feed) connected to the second antenna (522). According to various embodiments, the fourth feeding pad (554a) may be connected to the second antenna (522) via a second feeding line (554c). The fourth feeding pad (554a) may also be directly connected to the second antenna (522) without the second feeding line (554c). For example, the fourth feeding pad (554a) may be located on the inside of the substrate (501) at a first distance from the surface where the second antenna (522) is placed (e.g., the first surface (501a)). For example, the second coupling pad (554b) may be located on the inside of the substrate (501) at a second distance from the surface where the second antenna (522) is placed (e.g., the first surface (501a)). The second distance may be longer than the first distance. When an RF signal is transmitted from the second switch (512) to the fourth transmission line (544), the RF signal may be transmitted to the second antenna (522) through wireless coupling between the second coupling pad (554b) and the fourth feeding pad (554a). For convenience of explanation, the path through which the RF signal is transmitted from the second switch (512) to the second antenna (552) via the fourth transmission line (544), the second coupling pad (554b), and the fourth feeding pad (554a) may be referred to as the 'fourth RF path'. The fourth RF path may be referred to as an RF path utilizing 'coupling feeding' as it transmits the RF signal by coupling with the fourth feeding pad (554a) through the second coupling pad (554b), but is not limited to the above terminology.

[0068] According to various embodiments, at least one of the fourth feeding pad (554a) and / or the second feeding line (554c) connecting the fourth feeding pad (554a) to the second antenna (522) may be omitted. For example, an RF signal may be transmitted to the second antenna (522) by coupling between the second coupling pad (554b) and the second antenna (522). For example, the second coupling pad (554b) may have substantially the same area as the second antenna (522). According to various embodiments, the first distance between the second feeding pad (552a) and the first coupling pad (552b) may differ from the second distance between the fourth feeding pad (554a) and the second coupling pad (554b). For example, the second distance may be longer than the first distance.

[0069] According to various embodiments, a sensing circuit (e.g., a sensing unit (531) and a sensor IC (532)) can sense the proximity of an object (e.g., a human body) within a sensing area (e.g., whether the object exists or is located within a set first distance). For convenience of explanation, the proximity of an object is described as an example, but it is obvious that the detection of proximity may include the detection of contact or wearing of an object. For example, the sensing unit (531) can transmit a signal of sensing an object (e.g., a human body) within a sensing area to the sensor IC (532). Based on the signal received from the sensing unit (531), the sensor IC (532) can generate data (or information) corresponding to the distance to the object (e.g., a human body). Data (or information) corresponding to the distance to an object generated by the sensor IC (532) may be transmitted to a processor (e.g., the processor (120) of FIG. 1, the communication module (190), or the modem (211) of FIG. 2). Based on the data (or information) corresponding to the distance to an object received from the sensor IC (532), the processor may determine whether the sensed object is within a set distance (e.g., a first distance). If the sensor IC (532) is a proximity sensor or a grip sensor, the sensor IC (532) may transmit data (or information) indicating that an object is within the set distance when the distance to the sensed object is within the set distance (e.g., a first distance) to the processor. According to one embodiment, the processor can determine whether there is an external object in close proximity (or contact) to the electronic device (101) (or, the first antenna (521) and / or the second antenna (522) of the electronic device (101)) based on data (or information) received from the sensor IC (532). According to one embodiment, the processor can determine whether the electronic device (101) is worn on a user's body (e.g., head) based on data (or information) received from the sensor IC (532).According to various embodiments, the sensing circuit may be implemented in various ways. For example, the sensing circuit may detect the proximity (or contact) of an external object (e.g., a human body) using an antenna (e.g., a first antenna (521) and / or a second antenna (522)) without using a separate sensing unit (531). The sensor IC (532) may determine whether an external object (e.g., a human body) is present within a set distance based on a measurement related to the return loss of the antenna tuner. Additionally, the sensing circuit may be implemented by a touch sensor that determines whether a touch occurs based on the amount of change in the electric field. Alternatively, the sensing circuit may detect the proximity of an external object based on the amount of reflected infrared radiation emitted.

[0070] According to various embodiments, the operation of checking the proximity of an object (e.g., a human body) may be performed when a designated application (e.g., a call application, a multimedia application) is executed on the electronic device (101). For example, when a user presses an icon for a call function (e.g., a button containing text or an image), the electronic device (101) may check the proximity of the object. For example, when a communication connection is established with an external electronic device (e.g., electronic device (102), electronic device (104), electronic device (108), an access point, or a base station), the electronic device (101) may check the proximity of the object. For example, when the transmission / reception of a signal (e.g., data, voice) with an external electronic device is initiated, the electronic device (101) may check the proximity of the object. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be performed in advance before the designated application is executed on the electronic device (101). For example, determining whether an external object is detected in relation to the establishment of a communication connection may mean that the detection of the external object can be performed before or after the establishment of the communication connection. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be performed periodically while a designated application is running. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be stopped when the execution of the designated application ends. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be performed based on the determination that the frequency used for communication with an external electronic device is a designated frequency. For example, the operation of checking the proximity of an object (e.g., a human body) may be stopped if the frequency used for communication with an external electronic device changes from a designated frequency to another frequency.

[0071] According to one embodiment, the sensing unit (531) may be placed at various locations on the electronic device (101). For example, the sensing unit (531) may be placed at a location where the user holds the electronic device (101) with their hand to bring the earpiece speaker of the electronic device (101) to their ear during a call. For example, the sensing unit (531) may be placed around the earpiece speaker of the electronic device (101). For example, the sensing unit (531) may be placed at a location where the user holds the electronic device (101) with their hand to use data communication-related functions while looking at the screen of the display module (160).

[0072] According to one embodiment, the sensing unit (531) may include a touch sensor or a proximity sensor formed on the outer surface of the electronic device (101).

[0073] According to one embodiment, the electronic device (101) may select an RF path using direct feeding for one of the first antenna (521) (e.g., a first radiator or a first patch) and the second antenna (522) (e.g., a second radiator or a second patch), and select an RF path using coupling feeding for the other. For example, under a first specified condition, an RF path using direct feeding may be selected for both the first antenna (521) and the second antenna (522), and under a second specified condition, an RF path using direct feeding may be selected for the first antenna (521) but an RF path using coupling feeding may be selected for the second antenna (522). Under a third specified condition, an RF path using coupling feeding may be selected for both the first antenna (521) and the second antenna (522), and under a fourth specified condition, an RF path using coupling feeding may be selected for the first antenna (521) but an RF path using direct feeding may be selected for the second antenna (522). The first specified condition, the second specified condition, the third specified condition, and the fourth specified condition may relate to at least one of, for example, the type of communication function (e.g., whether it is a call function or a data communication function), the area of ​​contact with the human body (e.g., whether the contact area is larger or smaller than a set size), the location of contact with the human body (e.g., whether it is in contact with the face or only with the hand), the time of contact with the human body (e.g., whether it is in contact for more than a specified time), the strength of the transmission power, or the distance from the base station.

[0074] According to one embodiment, the sensing unit (531) may include a first sensing unit disposed around a first housing portion (e.g., a housing portion forming the left side) of the electronic device (101) and / or a second sensing unit disposed around a second housing portion (e.g., a housing portion forming the right side). The sensing unit (531) may further include a third sensing unit disposed around an antenna of the electronic device (101) (e.g., a first antenna (521) and / or a second antenna (522)). For example, when the electronic device (101) detects a specific external object (e.g., a human body) that is in close proximity to or in contact with the electronic device (101) through the first sensing unit and / or the second sensing unit, it may select an RF path using direct feeding for one of the first antenna (521) and the second antenna (522), and select an RF path using coupling feeding for the other. For example, when the electronic device (101) detects a specific external object (e.g., a human body) that is in close proximity to or in contact with the electronic device (101) through the third sensing unit, it may select an RF path that uses coupling feeding for both the first antenna (521) and the second antenna (522).

[0075] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may control the first switch (511) to be connected to the first RF path based on confirming that there is no object within the set distance (e.g., the first distance). For example, based on confirming that there is no object within the set distance, the processor may control the first switch (511) so that the first switch (511) is connected to the first transmission line (541) and not connected to the second transmission line (542). When the first switch (511) is connected to the first transmission line (541), the RF signal transmitted to the first transmission line (541) may be transmitted to the first antenna (521) through the first feeding pad (551). For example, the RF signal transmitted from the first switch (511) to the first transmission line (541) can be transmitted to the first antenna (521) through the first RF path using direct feeding.

[0076] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may switch the first switch (511) to disconnect from the first RF path and connect to the second RF path based on confirming that an object is within the set distance. For example, based on confirming that an object is within the set distance, the processor may control the first switch (511) to switch from being connected to the first transmission line (541) to being connected to the second transmission line (542). When the first switch (511) is connected to the second transmission line (542), the RF signal transmitted to the second transmission line (542) may be transmitted to the first antenna (521) through coupling with the first coupling (552b) and the second feeding pad (552a). For example, the RF signal transmitted from the first switch (511) to the second transmission line (542) can be transmitted to the first antenna (521) through the second RF path using coupling feeding.

[0077] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may control the second switch (512) to be connected to a third RF path based on confirming that there is no object within the set distance (e.g., the first distance). For example, based on confirming that there is no object within the set distance, the processor may control the second switch (512) so that the second switch (512) is connected to the third transmission line (543) and not connected to the fourth transmission line (544). When the second switch (512) is connected to the third transmission line (543), the RF signal transmitted to the third transmission line (543) may be transmitted to the second antenna (522) through the third feeding pad (553). For example, the RF signal transmitted from the second switch (512) to the third transmission line (543) can be transmitted to the second antenna (522) through the third RF path using direct feeding.

[0078] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may switch the second switch (512) to disconnect from the third RF path and connect to the fourth RF path based on confirming that an object is within the set distance (e.g., the first distance). For example, based on confirming that an object is within the set distance, the processor may control the second switch (512) to switch from being connected to the third transmission line (543) to being connected to the fourth transmission line (544). When the second switch (512) is connected to the fourth transmission line (544), the RF signal transmitted to the fourth transmission line (544) may be transmitted to the second antenna (522) through coupling with the second coupling (554b) and the fourth feeding pad (554a). For example, the RF signal transmitted from the second switch (512) to the fourth transmission line (544) can be transmitted to the second antenna (522) through the fourth RF path using coupling feeding.

[0079] According to various embodiments, the second antenna (522), the third transmission line (543), and the fourth transmission line (544) in FIG. 5 may be omitted. According to various embodiments, FIG. 5 illustrates that two antennas (521, 522) are connected to the switch (510), but it may be connected to three or more antennas. For example, if the switch (510) is connected to three or more antennas, the switch (510) may be connected via an RF path using coupling feeding with each antenna, based on confirming that there is an object within a set distance. If the switch (510) is connected to three or more antennas, the switch (510) may be connected via an RF path using direct feeding with each antenna, based on confirming that there is no object within a set distance.

[0080] According to various embodiments, when the coupling feeding is used, the position of the coupling pad (e.g., the first coupling pad (552b), or the second coupling pad (554b)) is positioned further away from the sensing direction (e.g., the direction in which the first surface (501a) of the substrate (e.g., PCB or FPCB) (501) faces) than the position of the feeding pad (e.g., the first feeding pad (551), or the third pad (553)), so that the APD may be lowered as described above in the description of FIG. 4a. Thus, by using coupling feeding in the RF path, the APD is lowered compared to the direct feeding, so power backoff may not be performed even if an object is in close proximity. By not performing the power backoff, the electronic device can transmit RF signals with a relatively high transmission power, thereby providing a relatively high throughput. However, the embodiments of the present disclosure are not intended to be limited thereto. According to one embodiment, the electronic device (101) may use coupling feeding and power backoff together when specified conditions are satisfied. The specified conditions may include, for example, when the area of ​​an external object close to the electronic device (101) is larger than a specified standard, when the external object maintains a state of closeness for more than a specified time, or when the electronic device (101) transmits power greater than a specified standard for more than a specified time. According to one embodiment, the electronic device (101) may adjust the magnitude of the power of the signal to be transmitted at least partially simultaneously while using coupling feeding when specific conditions are satisfied. Adjusting the transmission power intensity may include, depending on the condition, selecting one of a plurality of specified power offset values ​​and adding or subtracting the selected power offset value from the magnitude of the transmission power.

[0081] According to various embodiments, when an object is present within a set distance, if an RF signal is transmitted via an RF path using direct feeding rather than through an RF path using coupling feeding, power backoff of, for example, about 3.5 dB may be required according to the APD standard. On the other hand, when an object is present within a set distance, if an RF signal is transmitted via an RF path using coupling feeding, the long-distance performance (e.g., passive TRP (total radiated power) and active TRP) may be degraded by, for example, about 1.5 dB due to RF signal transmission through coupling, but performance can be improved by relatively about 2 dB by not performing 3.5 dB of power backoff, thereby providing relatively high throughput.

[0082] FIG. 6 illustrates a block diagram of an electronic device according to various embodiments.

[0083] Referring to FIG. 6, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a plurality of antennas, a switch (610) (e.g., a first switch (611), a second switch (612)), a first antenna (621) (e.g., a first radiator), and a second antenna (622) (e.g., a second radiator), and a sensing circuit. Each of the first antenna (621) and the second antenna (622) may be a component of a set of antennas composed of a plurality of antennas. Each of the first antenna (621) and the second antenna (622) may correspond to a patch antenna (224) and a patch antenna (225). However, the type of antenna is not limited to a patch antenna. The sensing circuit may include a sensing unit (631) (or sensor) and a sensor IC (632). The sensing unit (631) may include a sensing pattern. The sensing pattern may be positioned in close proximity to the first antenna (621) and / or the second antenna (622). The sensing pattern may include one or more sensors (e.g., conductors) each positioned between a radiator (e.g., a patch) and a radiator (e.g., a patch). The switch (610), the first antenna (621), the second antenna (622), and the sensing unit (631) may be positioned on a first surface (501a) of a substrate (e.g., a PCB or an FPCB) (501), and the sensor IC (632) may be positioned on a second surface (501b) opposite to the first surface (501a) of the substrate (501). The sensing unit (631) may be positioned between the first antenna (621) and the second antenna (622). The arrangement or position of each component shown in FIG. 6 is exemplary and is not limited thereto. The components of FIGS. 6 and FIG. 7 described below can be understood by referring to the description of the corresponding components included in FIG. 5.For example, the switch (610) and / or sensor IC (632) may be placed on a printed circuit board (e.g., PCB (210)) where the RFIC (215) is located, and the sensing unit (631) may be placed on a printed circuit board (e.g., FPCB (220)) where the first antenna (621) and the second antenna (622) are located.

[0084] According to various embodiments, the switch (610) (e.g., the first switch (611), or the second switch (612)) may be connected to at least one of the first antenna (621) or the second antenna (622) through at least one of the first transmission line (641), the second transmission line (642), the third transmission line (643), and the fourth transmission line (644). For example, the first switch (611) may be connected to the first antenna (621) through the first transmission line (641) or the second transmission line (642). The second switch (612) may be connected to the second antenna (622) through the third transmission line (643) or the fourth transmission line (644). According to one embodiment, the switch (610) (e.g., the first switch (611), or the second switch (612)) may be included within the modem (211), the IF / RFIC module (213), or the RFFE (217). According to one embodiment, the switch (610) (e.g., the first switch (611), or the second switch (612)) may be provided as a separate module. According to one embodiment, the switch (610) may transmit an RF signal (or, transmission signal, transmission power, transmission current) output from the RFIC (215) to the first antenna (621) (or the second antenna (622)) between the RFIC (215) and the first antenna (621) (or the second antenna (622)). For example, a switch (610) (e.g., a first switch (611), or a second switch (612)) may refer to at least one of hardware, software, or firmware that includes a structure capable of selecting one of a plurality of transmission lines based on at least one of the proximity of an external object or the strength of the transmission power, according to a command of a processor (e.g., a processor (210)). According to one embodiment, the first switch (611) may be configured to select one of a first transmission line (641) and a second transmission line (642) connected to a first antenna (621).According to one embodiment, the first switch (611) can maintain a connection between the other transmission line and the first antenna (621) while transmitting an RF signal to the selected transmission line among the first transmission line (641) and the second transmission line (642). According to one embodiment, the first switch (611) can be configured so that when one of the first transmission line (641) and the second transmission line (642) is connected to the first antenna (621), the other one is not connected to the first antenna (621).

[0085] According to various embodiments, one side of the first transmission line (641) may be connected to the first switch (611), and the other side of the first transmission line (641) may be connected to the first antenna (621) through the first feeding pad (651) (or feed section). For example, the first feeding pad (651) may be located on the surface of the substrate (501) where the first antenna (621) is placed (e.g., the first surface (501a)). An RF (radio frequency) signal may be transmitted from the first switch (611) to the first antenna (621) through the first transmission line (641) and the first feeding pad (651). For convenience of explanation, the path through which the RF signal is transmitted from the first switch (611) to the first antenna (621) via the first transmission line (641) and the first feeding pad (651) may be referred to as the 'first RF path'. In the first RF path, the first feeding pad (651) is connected in relative proximity to the first antenna (621), so it may be referred to as an RF path utilizing 'near feeding', but is not limited to the above terminology.

[0086] According to various embodiments, one side of the second transmission line (642) may be connected to the first switch (611), and the other side of the second transmission line (642) may be connected to the first antenna (621) through the second feeding pad (652) (or feed section). According to various embodiments, the second feeding pad (652) may be connected to the first antenna (621) through the first feeding line (621a). The second feeding pad (652) may also be directly connected to the first antenna (621) without the first feeding line (621a). An RF (radio frequency) signal may be transmitted from the first switch (611) to the first antenna (621) through the second transmission line (642), the second feeding pad (652), and the first feeding line (621a). For convenience of explanation, the path through which the RF signal is transmitted from the first switch (611) to the first antenna (621) via the second transmission line (642), the second feeding pad (652), and the first feeding line (621a) may be referred to as the 'second RF path'. In the second RF path, the second feeding pad (652) may be referred to as an RF path utilizing 'far feeding' as it is connected at a relative distance from the first antenna (621) compared to the first feeding pad (651), but is not limited to this term. Depending on various embodiments, at least one of the second feeding pad (652a) and / or the first feeding line (621a) connecting the second feeding pad (652a) to the first antenna (621) may be omitted.

[0087] According to various embodiments, one side of the third transmission line (643) may be connected to the second switch (612), and the other side of the third transmission line (643) may be connected to the second antenna (622) through the third feeding pad (653) (or feed section). For example, the third feeding pad (653) may be located on the surface of the substrate (501) where the second antenna (622) is placed (e.g., the first surface (501a)). An RF signal may be transmitted from the second switch (612) to the second antenna (622) through the third transmission line (643) and the third feeding pad (653). For convenience of explanation, the path through which the RF signal is transmitted from the first switch (611) to the second antenna (622) via the third transmission line (643) and the third feeding pad (653) may be referred to as the 'third RF path'. In the third RF path, the third feeding pad (653) is connected in relative proximity to the second antenna (622), so it may be referred to as an RF path utilizing 'near feeding', but is not limited to the above terminology.

[0088] According to various embodiments, one side of the fourth transmission line (644) may be connected to the second switch (612), and the other side of the fourth transmission line (644) may be connected to the second antenna (622) through the fourth feeding pad (654) (or feed section). According to various embodiments, the fourth feeding pad (654) may be connected to the second antenna (622) through the second feeding line (622a). The fourth feeding pad (654) may also be directly connected to the second antenna (622) without the second feeding line (622a). An RF (radio frequency) signal may be transmitted from the second switch (612) to the second antenna (622) through the fourth transmission line (644), the fourth feeding pad (654), and the second feeding line (622a). For convenience of explanation, the path through which the RF signal is transmitted from the second switch (612) to the second antenna (622) via the fourth transmission line (644), the fourth feeding pad (654), and the second feeding line (622a) may be referred to as the 'fourth RF path'. In the second RF path, the fourth feeding pad (654) may be referred to as an RF path utilizing 'far feeding' as it is connected relatively far from the second antenna (622) compared to the third feeding pad (653), but is not limited to this term. Depending on various embodiments, at least one of the fourth feeding pad (654) and / or the second feeding line (622a) connecting the fourth feeding pad (654) to the second antenna (622) may be omitted.

[0089] According to various embodiments, a sensing circuit (e.g., a sensing unit (631) and a sensor IC (632)) can sense the proximity of an object (e.g., a human body) within a sensing area (e.g., whether the object exists or is located within a set first distance). For convenience of explanation, the proximity of an object is described as an example, but it is obvious that the detection of proximity may include the detection of contact or wearing of an object. For example, the sensing unit (631) can transmit a signal of sensing an object (e.g., a human body) within a sensing area to the sensor IC (632). Based on the signal received from the sensing unit (631), the sensor IC (632) can generate data (or information) corresponding to the distance to the object (e.g., a human body). Data (or information) corresponding to the distance to an object generated by the sensor IC (632) may be transmitted to a processor (e.g., the processor (120) of FIG. 1, the communication module (190), or the modem (211) of FIG. 2). Based on the data (or information) corresponding to the distance to an object received from the sensor IC (632), the processor may determine whether the sensed object is within a set distance (e.g., a first distance). If the sensor IC (632) is a proximity sensor or a grip sensor, the sensor IC (632) may transmit data (or information) indicating that an object is within the set distance when the distance to the sensed object is within the set distance (e.g., a first distance) to the processor. According to one embodiment, the processor can determine whether there is an external object in close proximity (or contact) to the electronic device (101) (or the first antenna (621) and / or the second antenna (622) of the electronic device (101)) based on data (or information) received from the sensor IC (632). According to one embodiment, the processor can determine whether the electronic device (101) is worn on a user's body (e.g., head) based on data (or information) received from the sensor IC (632).According to various embodiments, the sensing circuit may be implemented in various ways. For example, the sensing circuit may detect the proximity (or contact) of an external object (e.g., a human body) using an antenna (e.g., a first antenna (621) and / or a second antenna (622)) without using a separate sensing unit (631). The sensor IC (632) may determine whether an external object (e.g., a human body) is present within a set distance based on a measurement related to the return loss of the antenna tuner. Additionally, the sensing circuit may be implemented by a touch sensor that determines whether a touch occurs based on the amount of change in the electric field. Alternatively, the sensing circuit may detect the proximity of an external object based on the amount of reflected infrared radiation emitted.

[0090] According to various embodiments, the operation of checking the proximity of an object (e.g., a human body) may be performed when a designated application (e.g., a call application, a multimedia application) is executed on the electronic device (101). For example, when a user presses an icon for a call function (e.g., a button containing text or an image), the electronic device (101) may check the proximity of the object. For example, when a call is connected and the exchange of transmission and reception tones begins, the electronic device (101) may check the proximity of the object. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be performed in advance before the designated application is executed on the electronic device (101). For example, determining whether an external object is detected in relation to the establishment of a communication connection may mean that the detection of the external object may be performed before or after the establishment of the communication connection. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be performed periodically while the designated application is executed. According to one embodiment, the operation of checking the proximity of an object (e.g., a human body) may be stopped when the execution of a specified application is terminated.

[0091] According to one embodiment, the sensing unit (631) may be placed at various locations on the electronic device (101). For example, the sensing unit (631) may be placed at a location where the user holds the electronic device (101) with their hand to bring the earpiece speaker of the electronic device (101) to their ear during a call. For example, the sensing unit (631) may be placed around the earpiece speaker of the electronic device (101). For example, the sensing unit (631) may be placed at a location where the user holds the electronic device (101) with their hand to use data communication-related functions while looking at the screen of the display module (160).

[0092] According to one embodiment, the sensing unit (631) may include a touch sensor or a proximity sensor formed on the outer surface of the electronic device (101).

[0093] According to one embodiment, the electronic device (101) may select an RF path using near-field feeding for one of the first antenna (621) (e.g., a first radiator or a first patch) and the second antenna (622) (e.g., a second radiator or a second patch), and select an RF path using far-field feeding for the other. For example, under a first specified condition, an RF path using near-field feeding may be selected for both the first antenna (621) and the second antenna (622), and under a second specified condition, an RF path using near-field feeding may be selected for the first antenna (621), but an RF path using far-field feeding may be selected for the second antenna (622). Under a third specified condition, an RF path using far-field feeding may be selected for both the first antenna (621) and the second antenna (622), and under a fourth specified condition, an RF path using far-field feeding may be selected for the first antenna (621), but an RF path using near-field feeding may be selected for the second antenna (622). The first specified condition, the second specified condition, the third specified condition, and the fourth specified condition may relate to at least one of, for example, the type of communication function (e.g., whether it is a call function or a data communication function), the area of ​​contact with the human body (e.g., whether the contact area is larger or smaller than a set size), the location of contact with the human body (e.g., whether it is in contact with the face or only with the hand), the time of contact with the human body (e.g., whether it is in contact for more than a specified time), the strength of the transmission power, or the distance from the base station.

[0094] According to one embodiment, the sensing unit (631) may include a first sensing unit disposed around a first housing portion (e.g., a housing portion forming the left side) of the electronic device (101) and / or a second sensing unit disposed around a second housing portion (e.g., a housing portion forming the right side). The sensing unit (631) may further include a third sensing unit disposed around an antenna of the electronic device (101) (e.g., a first antenna (621) and / or a second antenna (622)). For example, when the electronic device (101) detects a specific external object (e.g., a human body) that is in close proximity to or in contact with the electronic device (101) through the first sensing unit and / or the second sensing unit, it may select an RF path using short-range feeding for one of the first antenna (621) and the second antenna (622), and select an RF path using long-range feeding for the other. For example, when the electronic device (101) detects a specific external object (e.g., a human body) that is in close proximity to or in contact with the electronic device (101) through the third sensing unit, it may select an RF path that uses remote feeding for both the first antenna (621) and the second antenna (622).

[0095] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may control the first switch (611) to be connected to the first RF path based on confirming that there is no object within the set distance (e.g., the first distance). For example, based on confirming that there is no object within the set distance, the processor may control the first switch (611) so that it is connected to the first transmission line (641) and not connected to the second transmission line (642). When the first switch (611) is connected to the first transmission line (641), the RF signal transmitted to the first transmission line (641) may be transmitted to the first antenna (621) through the first feeding pad (651). For example, the RF signal transmitted from the first switch (611) to the first transmission line (641) can be transmitted to the first antenna (621) through the first RF path using near-field feeding.

[0096] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may switch the first switch (611) to disconnect from the first RF path and connect to the second RF path based on confirming that an object is within the set distance. For example, based on confirming that an object is within the set distance, the processor may control the first switch (611) to switch from being connected to the first transmission line (641) to being connected to the second transmission line (642). When the first switch (611) is connected to the second transmission line (642), the RF signal transmitted to the second transmission line (642) may be transmitted to the first antenna (621) through the second feeding pad (652) and / or the first feeding line (621a). For example, the RF signal transmitted from the first switch (611) to the second transmission line (642) can be transmitted to the first antenna (621) through the second RF path using long-distance feeding.

[0097] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may control the second switch (612) to be connected to a third RF path based on confirming that there is no object within the set distance (e.g., the first distance). For example, based on confirming that there is no object within the set distance, the processor may control the second switch (612) so that the second switch (612) is connected to the third transmission line (643) and not connected to the fourth transmission line (644). When the second switch (612) is connected to the third transmission line (643), the RF signal transmitted to the third transmission line (643) may be transmitted to the second antenna (622) through the third feeding pad (653). For example, the RF signal transmitted from the second switch (612) to the third transmission line (643) can be transmitted to the second antenna (622) through the third RF path using near-field feeding.

[0098] According to various embodiments, a processor (e.g., the processor (120) of FIG. 1 or the communication module (190) or the modem (211) of FIG. 2) may switch the second switch (612) to disconnect from the third RF path and connect to the fourth RF path based on confirming that an object is within the set distance (e.g., the first distance). For example, based on confirming that an object is within the set distance, the processor may control the second switch (610) to switch or transition the second switch (612) from being connected to the third transmission line (643) to being connected to the fourth transmission line (644). When the second switch (612) is connected to the fourth transmission line (644), the RF signal transmitted to the fourth transmission line (644) may be transmitted to the second antenna (622) through the fourth feeding pad (654) and / or the second feeding line (622a). For example, the RF signal transmitted from the second switch (612) to the fourth transmission line (644) can be transmitted to the second antenna (622) through the fourth RF path using long-distance feeding.

[0099] According to various embodiments, the second antenna (622), the third transmission line (643), and the fourth transmission line (644) in FIG. 6 may be omitted. According to various embodiments, FIG. 6 illustrates that two antennas (621, 622) are connected to the switch (610), but it may be connected to three or more antennas. For example, if the switch (610) is connected to three or more antennas, the switch (610) may be connected to each antenna via an RF path using long-range feeding based on confirming that there is an object within a set distance. If the switch (610) is connected to three or more antennas, the switch (610) may be connected to each antenna via an RF path using short-range feeding based on confirming that there is no object within a set distance.

[0100] According to various embodiments, when using the far-distance feeding, the position of the feeding pad (e.g., second feeding pad (652) or fourth feeding pad (654)) connected to each antenna (621, 622) is placed at a relatively greater distance from the antenna (621, 622) than the position of the feeding pad (e.g., first feeding pad (651) or third feeding pad (653)) using the near-distance feeding, so that the APD may be lowered as described above in the description of FIG. 4a. Thus, by using far-distance feeding in the RF path, the APD is lowered compared to the near-distance feeding, so power backoff may not be performed even if an object is in close proximity. By not performing the power backoff, the electronic device can transmit RF signals with a relatively high transmit power, thereby providing a relatively high throughput. However, the embodiments of the present disclosure are not intended to be limited thereto. According to one embodiment, the electronic device (101) may use remote feeding and power backoff together when specified conditions are satisfied. The specified conditions may include, for example, when the area of ​​an external object close to the electronic device (101) is larger than a specified standard, when the external object maintains a state of closeness for more than a specified time, or when the electronic device (101) transmits power greater than a specified standard for more than a specified time. According to one embodiment, the electronic device (101) may adjust the magnitude of the power of the signal to be transmitted at least partially simultaneously while using remote feeding when specific conditions are satisfied. Adjusting the transmission power intensity may include, depending on the condition, selecting one of a plurality of specified power offset values ​​and adding or subtracting the selected power offset value from the magnitude of the transmission power.

[0101] FIG. 7 illustrates a block diagram of an electronic device according to various embodiments.

[0102] Referring to FIG. 7, a feeding cover may be placed on a second feeding pad (652) and / or a fourth feeding pad (654) positioned on an RF path utilizing remote feeding in the electronic device of FIG. 6. A detailed description of the configuration and function identical to FIG. 6 will be omitted. For example, a first feeding cover (710) may be placed on the upper part of the second feeding pad (652), and a second feeding cover (720) may be placed on the upper part of the fourth feeding pad (654). The first feeding cover (710) and the second feeding cover (720) may be placed to reduce the electromagnetic wave effect that may increase as the corresponding feeding pad is exposed relatively to the outer surface of the substrate (501) without being covered by an antenna (e.g., a first antenna (621) or a second antenna (622)). The first feeding cover (710) and the second feeding cover (720) may be formed from a conductive material. The first feeding cover (710) and the second feeding cover (720) may be connected to the ground of the substrate (501).

[0103] According to various embodiments, when using remote feeding, the APD can be lowered as described above in the description of FIG. 4b by placing a feeding cover (e.g., first feeding cover (710) or second feeding cover (720)) on top of a feeding pad (e.g., second feeding pad (652) or fourth feeding pad (654)) connected to each antenna (621, 622).

[0104] FIG. 8 illustrates a flowchart for explaining the operation method of an electronic device according to various embodiments.

[0105] In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0106] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a sensing circuit (e.g., a sensing unit (531), a sensor IC (532)), an antenna (521, 522) configured to radiate an RF signal, and a switch (510) (e.g., a first switch (511), a second switch (512)). The electronic device may include a memory (e.g., the memory (130) of FIG. 1) that stores instructions and includes one or more storage media. The electronic device may include at least one processor (e.g., the processor (120) of FIG. 1 or a communication module (190) or a modem (211) of FIG. 2) that includes a processing circuit. The instructions may cause the electronic device to perform at least one operation when executed by the processor, either individually or collectively.

[0107] According to various embodiments, an electronic device (101) (e.g., at least one of a processor (120) or a communication module (190) or a modem (211) of FIG. 2) can determine, in operation 802, whether an object is present within a first distance by means of the sensing circuit. For example, the electronic device (101) can determine whether a specific external object (e.g., a human body) is in close proximity (e.g., in contact) to the electronic device (101).

[0108] According to various embodiments, in operation 804, if the result of the check is not confirmed to be that an object exists within a first distance (operation 804-No), the electronic device (101) may control the switch in operation 806 to be connected to the antenna via a first RF path using direct feeding. The first RF path may correspond to the first RF path of FIG. 5 or the third RF path of FIG. 5. For example, the electronic device (101) may select the RF path using direct feeding among the RF path using direct feeding and the RF path using coupling feeding when a specific external object (e.g., a human body) is not close to the electronic device (101). The electronic device (101) may supply transmission current to the antenna via the selected RF path.

[0109] According to various embodiments, in operation 804, if the result of the verification confirms that an object exists within a first distance (operation 804-e), the electronic device (101) may control the switch in operation 808 to be connected to the antenna via a second RF path using coupling feeding. The second RF path may correspond to the second RF path of FIG. 5 or the fourth RF path of FIG. 5. For example, the electronic device (101) may select the RF path using coupling feeding from among the RF path using direct feeding and the RF path using coupling feeding, based at least in part on the determination that a specific external object (e.g., a human body) has approached the electronic device (101). According to one embodiment, an electronic device (101) may select an RF path using coupling feeding among an RF path using direct feeding and an RF path using coupling feeding when a specific external object (e.g., a human body) is in close proximity to the electronic device (101) and the magnitude of the transmission power of the electronic device (101) satisfies a specified criterion. The electronic device (101) may supply transmission current to an antenna through the selected RF path.

[0110] FIG. 9 illustrates a flowchart for explaining the operation method of an electronic device according to various embodiments.

[0111] In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0112] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a sensing circuit (e.g., a sensing unit (531), a sensor IC (532)), an antenna (521, 522) configured to radiate an RF signal, and a switch (510) (e.g., a first switch (511), a second switch (512)). The electronic device may include a memory (e.g., the memory (130) of FIG. 1) that stores instructions and includes one or more storage media. The electronic device may include at least one processor (e.g., the processor (120) of FIG. 1 or a communication module (190) or a modem (211) of FIG. 2) that includes a processing circuit. The instructions may cause the electronic device to perform at least one operation when executed by the processor, either individually or collectively.

[0113] According to various embodiments, an electronic device (101) (e.g., at least one of a processor (120) or a communication module (190) or a modem (211) of FIG. 2) may maintain a radio resource control (RRC) connection state in operation 902.

[0114] According to various embodiments, the electronic device (101) can determine whether an object exists within a first distance by the sensing circuit in the RRC connection state (or call connection state) in operation 904. For example, the electronic device (101) can determine whether a specific external object (e.g., a human body) is in close proximity (e.g., in contact) to the electronic device (101).

[0115] According to various embodiments, in operation 906, if the result of the check is not confirmed to be that an object exists within a first distance (operation 906-No), the electronic device (101) may control the switch in operation 908 to be connected to the antenna via a first RF path using direct feeding. The first RF path may correspond to the first RF path of FIG. 5 or the third RF path of FIG. 5. For example, the electronic device (101) may select the RF path using direct feeding among the RF path using direct feeding and the RF path using coupling feeding when a specific external object (e.g., a human body) is not close to the electronic device (101). The electronic device (101) may supply transmission current to the antenna via the selected RF path.

[0116] According to various embodiments, in operation 906, if the result of the check confirms that an object exists within a first distance (operation 906-yes), the electronic device (101) may check in operation 910 whether the current frequency band corresponds to a specified frequency band. For example, the specified frequency band may correspond to a frequency band (e.g., 6 GHz to 60 GHz) set to apply power backoff according to the APD criteria.

[0117] According to various embodiments, in operation 910, if the result of the verification is confirmed to be that the current frequency band corresponds to a specified frequency band (operation 910-e), the electronic device (101) may control the switch in operation 912 to be connected to the antenna through a second RF path using coupling feeding. The second RF path may correspond to the second RF path of FIG. 5 or the fourth RF path of FIG. 5. For example, if the electronic device (101) confirms that the current frequency band corresponds to a specified frequency band, it may select the RF path using coupling feeding among the RF path using direct feeding and the RF path using coupling feeding. According to one embodiment, an electronic device (101) may select an RF path using coupling feeding among an RF path using direct feeding and an RF path using coupling feeding when a specific external object (e.g., a human body) is in close proximity to the electronic device (101), the frequency band is set back-off, and the magnitude of the transmission power of the electronic device (101) satisfies a specified criterion. The electronic device (101) may supply transmission current to an antenna through the selected RF path.

[0118] According to various embodiments, in operation 910, if the result of the check is that the current frequency band does not correspond to the specified frequency band (operation 910-No), the electronic device (101) may control the switch in operation 908 to be connected to the antenna via a first RF path using direct feeding. The first RF path may correspond to the first RF path of FIG. 5 or the third RF path of FIG. 5. For example, the electronic device (101) may select the RF path using direct feeding among the RF path using direct feeding and the RF path using coupling feeding when a specific external object (e.g., a human body) does not correspond to the specified frequency band even when it approaches the electronic device (101). The electronic device (101) may supply transmission current to the antenna via the selected RF path.

[0119] FIG. 10 illustrates a flowchart for explaining the operation method of an electronic device according to various embodiments.

[0120] In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0121] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a sensing circuit (e.g., a sensing unit (531), a sensor IC (532)), an antenna (521, 522) configured to radiate an RF signal, and a switch (510) (e.g., a first switch (511), a second switch (512)). The electronic device may include a memory (e.g., the memory (130) of FIG. 1) that stores instructions and includes one or more storage media. The electronic device may include at least one processor (e.g., the processor (120) of FIG. 1 or a communication module (190) or a modem (211) of FIG. 2) that includes a processing circuit. The instructions may cause the electronic device to perform at least one operation when executed by the processor, either individually or collectively.

[0122] According to various embodiments, an electronic device (101) (e.g., at least one of a processor (120) or a communication module (190) or a modem (211) of FIG. 2) may maintain a radio resource control (RRC) connection state in operation 1002.

[0123] According to various embodiments, the electronic device (101) can determine whether an object exists within a first distance by the sensing circuit in the RRC connection state (or call connection state) in operation 1004. For example, the electronic device (101) can determine whether a specific external object (e.g., a human body) is in close proximity (e.g., in contact) to the electronic device (101).

[0124] According to various embodiments, in operation 1006, if the result of the check is not confirmed to be that an object exists within a first distance (operation 1006-No), the electronic device (101) may control the switch in operation 1008 to be connected to the antenna via a first RF path using direct feeding. The first RF path may correspond to the first RF path of FIG. 5 or the third RF path of FIG. 5. For example, the electronic device (101) may select the RF path using direct feeding among the RF path using direct feeding and the RF path using coupling feeding when a specific external object (e.g., a human body) is not close to the electronic device (101). The electronic device (101) may supply transmission current to the antenna via the selected RF path.

[0125] According to various embodiments, in operation 1006, if the result of the check confirms that an object exists within a first distance (operation 1006-yes), the electronic device (101) may check in operation 1010 whether the current frequency band corresponds to a specified frequency band. For example, the specified frequency band may include a frequency band in which power backoff is set according to an APD standard.

[0126] According to various embodiments, in operation 1010, if the result of the check is that the current frequency band does not correspond to the specified frequency band (operation 1010-No), the electronic device (101) may control the switch in operation 1008 to be connected to the antenna via a first RF path using direct feeding. The first RF path may correspond to the first RF path of FIG. 5 or the third RF path of FIG. 5. For example, the electronic device (101) may select the RF path using direct feeding among the RF path using direct feeding and the RF path using coupling feeding when a specific external object (e.g., a human body) does not correspond to the specified frequency band even when it approaches the electronic device (101). The electronic device (101) may supply transmission current to the antenna via the selected RF path.

[0127] According to various embodiments, in operation 1010, if the result of the verification confirms that the current frequency band corresponds to a specified frequency band (operation 1010-e), the electronic device (101) can check in operation 1012 whether the power backoff value exceeds a set value related to coupling feeding. The power backoff value may correspond to a value that reduces power in the electronic device when an APD condition is met according to an APD criterion. The set value related to coupling feeding may correspond to antenna performance (e.g., TRP) that is lowered when the RF path is changed from direct feeding to coupling feeding. For example, if the power backoff value is set to 3.5 dB, when an object approaches the electronic device and the electronic device meets an APD condition, the electronic device may reduce the transmission power by 3.5 dB. The set value related to coupling feeding may be set as the difference in TRP between direct feeding and coupling feeding measured for each channel at each frequency, as shown in described later. For example, if the power backoff value is 3.5 dB and the setting value related to coupling feeding is 1.5 dB, the electronic device (101) can confirm that the power backoff value exceeds the setting value related to coupling feeding. In this case, even if switching from direct feeding to coupling feeding, the loss of antenna performance is smaller than the power value reduced by the power backoff, so switching to coupling feeding in an APD situation can provide relatively high throughput.

[0128] According to various embodiments, in operation 1012, if the power backoff value is found to exceed a set value related to coupling feeding as a result of the verification (operation 1012-e), the electronic device (101) may control the switch to be connected to the antenna via a second RF path using coupling feeding in operation 1016. The second RF path may correspond to the second RF path of FIG. 5 or the fourth RF path of FIG. 5. For example, if the electronic device (101) finds that the current frequency band corresponds to a specified frequency band and the power backoff value exceeds a set value related to coupling feeding, it may select the RF path using coupling feeding among the RF path using direct feeding and the RF path using coupling feeding. According to one embodiment, an electronic device (101) may select an RF path using coupling feeding among an RF path using direct feeding and an RF path using coupling feeding when a specific external object (e.g., a human body) is in close proximity to the electronic device (101), the frequency band is set for back-off, the power back-off value exceeds a set value related to coupling feeding, and the magnitude of the transmission power of the electronic device (101) satisfies a specified criterion. The electronic device (101) may supply transmission current to an antenna through the selected RF path.

[0129] According to various embodiments, in operation 1012, if it is confirmed that the power back-off value does not exceed the set value associated with coupling feeding (operation 1012-No), the electronic device (101) can back-off the power in operation 1014 and control the switch to be connected to the antenna through an RF path using direct feeding (e.g., the first RF path of FIG. 5, or the third RF path of FIG. 5) in operation 1008.

[0130] FIGS. 11a and FIGS. 11b are drawings for explaining the operation according to the gripping form of an electronic device according to various embodiments.

[0131] Embodiments of the present disclosure may be applied to wearable (e.g., AR (augmented reality) glasses), rollable, foldable, or multi-foldable electronic devices. A foldable electronic device (1100) (e.g., the electronic device (101) of FIG. 1) may include a flexible display comprising housing portions (e.g., a first housing (1110) and a second housing (1120)) rotatably connected to each other with respect to a folding axis, and display portions (e.g., a first display area and a second display area) accommodated in said housings. Between said first housing and said second housing, a hinge assembly may be included that is coupled to each housing and supports a folding function. Between said first housing and said second housing, a hinge housing may be disposed to accommodate at least a portion of said hinge assembly. The foldable electronic device may include at least one sensor (e.g., accelerometer, geomagnetic sensor, gyroscope, Hall sensor) that detects a folding state / unfolding state and / or a folding motion / unfolding motion. The multi-foldable electronic device may include a second housing rotatably connected to a first housing with respect to a first folding axis. The multi-foldable electronic device may include a third housing rotatably connected to a second housing with respect to a second folding axis. The multi-foldable electronic device may include a flexible display comprising a first display area, a second display area, and a third display area, each accommodated in the first housing, the second housing, and the third housing, respectively. The folding axis of the foldable electronic device may support an in-folding or out-folding method. The in-folding method may correspond to a method in which corresponding display areas are folded in a direction facing each other, and the out-folding method may correspond to a method in which corresponding display areas are folded in a direction not facing each other.The first folding axis of the above-described multi-foldable electronic device enables out-folding, and the second folding axis enables in-folding.

[0132] According to various embodiments, as illustrated in FIG. 11a, when the first housing (1110) and the second housing (1120) of the electronic device (1100) are unfolded, and it is confirmed that a user is holding the electronic device with their hand (1130) and performing data communication (e.g., multimedia streaming), the electronic device (1100) can transmit a transmission signal to an antenna using the aforementioned coupling feeding. For example, when the user holds the electronic device with their hand (1130) while the electronic device (1100) is unfolded, the user's body or head may remain separated from the electronic device (1100).

[0133] According to various embodiments, based on the fact that voice communication (e.g., a call) is performed in a folded state with the first housing (1110) and the second housing (1120) of the electronic device (1100) as illustrated in FIG. 11b, the electronic device (1100) may transmit a transmission signal to an antenna using the aforementioned coupling feeding and / or power backoff. For example, when the electronic device (1100) is in a folded state and a user holds it with their hand (1134) to perform a voice call, a part of the user's body (e.g., ear (1131), mouth (1132), jaw (1133), hand (1134), finger (1135)) may come into contact with or be in close proximity to the electronic device (1100).

[0134] According to various embodiments, the foldable electronic device or the multi-foldable electronic device may transmit a transmission signal transmitted to a first antenna (e.g., the first antenna (521) of FIG. 5) using direct feeding, based on the fact that data communication (e.g., multimedia streaming) is performed in the unfolded state as shown in FIG. 11a, and transmit a transmission signal transmitted to a second antenna (e.g., the second antenna (522) of FIG. 5) using coupling feeding. According to various embodiments, the foldable electronic device or the multi-foldable electronic device may transmit both transmission signals transmitted to the first antenna (e.g., the first antenna (521) of FIG. 5) and the second antenna (e.g., the second antenna (522) of FIG. 5) using coupling feeding, based on the fact that voice communication (e.g., a call) is performed in the folded state as shown in FIG. 11b.

[0135] FIG. 12 is a graph showing the total radiation efficiency by frequency according to various embodiments.

[0136] Referring to FIG. 12, according to various embodiments, when an RF signal is transmitted through an RF path using coupling feeding (1212) in an HB (high-frequency band) frequency band (1210) (e.g., N41), it can be seen that the long-distance performance (e.g., passive TRP (total radiated power) and active TRP) is reduced by the RF signal transmission through coupling, and the total radiation efficiency is reduced by about 1.5 dB compared to direct feeding (1211).

[0137] According to one embodiment, referring to below, it can be seen that the TRP in the HB frequency band (e.g., N41) is somewhat reduced in coupling feeding compared to direct feeding for each channel.

[0138] Frequency band N41_SA(TDD) mode TRP Channel (CH) L(low) M(medium) H(high) Direct feeding 17.83 16.74 15.99 Coupling feeding 16.13 15.52 15.47 Difference value (delta) -1.70 -1.22 -0.52

[0139] As described above, the value at which TRP is reduced by the coupling feeding can be set to a value related to the coupling feeding. For example, if the power value reduced by power backoff is 3.5 dB and the setting value related to the coupling feeding is 1.5 dB, then even if switching from direct feeding to coupling feeding, the loss of antenna performance is smaller than the power value reduced by power backoff, so switching to coupling feeding in an APD situation can provide relatively high throughput.

[0140] FIG. 13a is a diagram showing the SAR in direct feeding according to various embodiments. FIG. 13b is a diagram showing the SAR in direct feeding according to various embodiments. FIG. 13c is a diagram showing the SAR in coupling feeding according to various embodiments.

[0141] Figure 13a shows the SAR for each channel (e.g., L (low) channel, M (medium) channel, H (high) channel) when the transmit power is 25.5 dBm in direct feeding, and Figure 13b shows the SAR for each channel when the transmit power is 22.0 dBm due to power backoff in direct feeding. Figure 13c shows the SAR for each channel when the transmit power is 25.5 dBm without power backoff in coupling feeding.

[0142] According to various embodiments, the experimental results of FIGS. 13a, FIGS. 13b, and FIGS. 13c can be summarized as shown in Table 3 below.

[0143] Frequency band N41_SA(TDD) mode Body 0mm SAR Channel (CH) L(low) M(medium) H(high) Direct feeding 25.5dBm 3.98 3.87 3.66 22.0dBm 3.12 2.98 3.01 Coupling feeding 25.5dBm 3.24 3.02 2.98

[0144] Referring to above, it can be seen that the SAR in each channel when power back-off is applied from 25.5 dBm to 22.0 dBm for direct feeding transmission power is similar to the SAR when power back-off is not applied in coupling feeding. Therefore, the SAR or APD criteria can be satisfied by changing the feeding method from direct feeding to coupling feeding without excessive back-off according to the SAR or APD criteria when an object approaches.

[0145] According to one embodiment, the electronic device (101) may include a sensing circuit (531, 532), an antenna (521, 522) configured to radiate an RF signal, and a switch (510). The electronic device may include a memory (130) that stores instructions and includes one or more storage media.
